OLIVE` CRUSHER AND PITTER.

SPECIFICATION forming part of Letters Patent No. 717,245, dated December 30, 1902 Application filed September 25, 1900.` Serial No. 31,121. (No model.)

ment in Olive Crushers and Pitters, of which the following is a full, clear, and exact description. y t

The purpose of this invention is to provide means for separating the stones'or pits from4 olives, so that oil may be made from the pure olive pulp and, if desired, a second class of oil may be made from the pits and from such pulp as may cling thereto after the separation. This end we attain by a peculiarlyconstructed machine which gratesor grinds the olives and presses the pulp through a sieve, causing the pits to be expelledfrom the machine at a'different point, and thus effect the desiredv separation.

This specification is the disclosure of one form of the invention, while the claims dene the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the inven-y tion. Fig. 2 is a vertical .section thereof. Fig. 3 is a plan of the bed of themachine, and Fig. is an inverted plan of the rotating macerator or bur.

The machine is constructed on a suitable framing and has a bed-plate 5, with a circu` lar opening therein occupying the major portion of the plate, as indicated best in Fig. 3.' Over this opening is arranged a woven-wire fabric 6, which may be of any preferred construction and provided on its'under side with bars for sustaining it and lending a certain degree of rigidity thereto. Around the opening in the bed-plate 5 is erected a perpendicular wall or flange 8, provided at one side ofthe machine with extensions Sa, forming a discharge-chute for the pits. This chute delivers the pits into a pan or vat 9 at the bottom of the machine, at one side thereof, as shown in Figs. 1 and 2. On the screen or wire fabric 6 is'arranged a helical bar 10, the outermost convolution of which reaches to the wall or flange 8, so that a helical way is produced on the screen 6, through which way theolives are caused to travel during the process of Ina'ceration and separation, as will be fully described hereinafter, the pits reaching the outer convolution of said helical way to be discharged between the extensions 8 of the flange 8.

Arranged over the screen 6 and working inside of the flange 8 is a macerator or bur,

which is circularin form and comprises an upper or body` disk 1l, to the under side of which is fastened a metallic plate 12, and to the under side of this plate a wire screen 14E is fastenedtthis screen being arranged to work on the olives to macerate the same, and the macerator or bur serves to press the pulp or fruit through the screen 6. The macerator revolves over the bed of the machine and causes the olives to travel through the spiral way formed by the rod 10. The rod or bar 10 is provided (see Fig. 3) with a number of spring-lingers 10, which are attached at one end to the bar 10 and which have the other ends free, the fingers projecting toward the origin of the helix and serving to colncentrate theV olives, so that they may be eectively crushed, the fingers also yielding under superior pressure, thus avoiding clogging the machine. The macerator is mounted on -a vertical drive-shaft 15, the lower end Iof `which is stepped in a suitable bearing 16,

just below the screen 6. For the purpose of attaching the macerator to the shaft 15 a box "17 is attached to the macerator and provided fries on the body-plate 11 thereof a hopper 19,

and this hopper discharges upon the screen 6 through an opening 2O in the macerator. The olives are fed to the hopper 19 from a stationary hopper 21. The shaft 15 is provided with a collar 22, fast thereto, this collar bearing against the stationary part of the framing to prevent the shaft 15 and the attached macerator from yielding upwardly. The shaft 15 may be driven manually or by other IOO power through the medium of gearing 23 of any desired form. The olives to be treated are placed in the hopper 21 and from thence discharged into the hopper 19, which revolves continuously with the macerator. The olives then pass through the opening 2O onto the bed-screen (i, rthen being discharged at approximately the center of this screen, and therefore in the immediate vicinity of the Vortex of the helical Way thereon. As the macerator revolves the olives are rolled throughout this way and are crushed by the action of the parts between which they hear, the pulp being pressed through the screen 6 and falling on a chute 24, mounted below the screen, the chute 24 delivering to a pan or vat 25, situated at the base of the machine. The seeds or pits, with the small particles of the fruit which may yet cling thereto, are discharged into the vat 9. Therefore the two products are separated from each other and may be treated separately according to the desire of the operator.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. A crushing and separating apparatus, havingaperforated bed,a helical bar arranged thereon to form a helical way, a macerator or bur turning on the bed, and a 'feed member carried by the maeerator and turning therewith and discharging through the macerator into the bed in the vicinity of the vortex of the said helical way.

2. A crushing and macerating apparatus, having a perforated bed with a helical way thereon, a spring finger or fingers projecting into said Way, and a bur or inacerator turning on the bed.

In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
